Unhappy [Q] Previous problem with phone reporting no charge

I realized the mistake in my title...reporting NO charge.

I previously posted about how after clearing my battery stats it was reporting a 0% charge. I was able to leave it on the CWM screen for upwards of 5-6 hours, but the instant it loads up the OS the phone buzzes and turns off.

Now:
I got a new battery today and it appears that the battery is NOT the issue. The phone still reports a 0% charge, regardless of how long I leave it on the charger.


I'm unsure of how this could have happened, and I was curious if there was a way to completely reset the phone. IE: Every file exactly where it was when I first booted it up.

Any help would be great. I have an XPERIA Play as a back up, but I'd rather have my Thrill back.

Thanks in advance.
